Rogue Rats of Nitropolis

The top prize is capped at 25,000x your stake. On a $1 spin that is $25,000; on $0.20 it is $5,000. When the cap is reached the round usually ends immediately.

Multipliers are applied to wins as they land; in many games several multipliers add together or multiply each other, which is where the largest wins come from.

RTP is a long-run average across millions of spins. Any single session can finish far above or below it, especially on a high volatility game.

The published hit frequency is 33%, meaning roughly one spin in 3.0 returns something — though many of those wins are smaller than the stake.

Free spins

A bonus round of spins played at no cost to your balance, usually triggered by landing three or more scatter symbols. Wins during the round are added to your balance, and many games let you retrigger extra spins.

Multipliers

Multipliers increase a win by a set factor, such as 2x or 10x. They can be attached to symbols, applied to a whole spin, or grow during a feature, and are a main driver of the biggest wins.

Bonus buy

Lets you pay a fixed multiple of your stake to enter the bonus feature straight away instead of waiting for it to trigger. It raises variance considerably and is not available in every country (it is banned in the UK).

Multiple bonus buys

Several feature-buy options at different prices, each starting a different version of the bonus round.

Symbol upgrades

Lower-paying symbols are transformed into higher-paying ones during a feature.

• Treat bonus buys as high-risk. Buying the feature concentrates your budget into a few large-variance rounds. Many results return less than the price paid. Read our bonus buy guide first.
• Bonus wagering: at 94% RTP, clearing $1,000 of wagering costs about $60.00 on average. Check the bonus terms, as some casinos exclude specific games. Run your numbers in the wagering calculator.
• Set limits before you spin. Decide your loss limit and session time in advance and stop when you reach either. No pattern or betting system changes the outcome of a spin.
